The Mass Distribution of Transiting Exoplanets Corrected for Observational Selection Effects

摘要

The mass distribution of transiting exoplanets has been corrected for observational selection effects: the probability of a mass determination (for planets detected by the Kepler Space Telescope) and the probability of a transiting configuration. The corrected mass distribution of exoplanets can be fitted by a power law with an exponent of -2(-0.16)(+0.1):dN/dm proportional to m(-0.16)(-2)(+0.1). Two minima corresponding to 0.3-0.7 and 4-7 Jupiter masses have been revealed.
